There are various equivalent formulations of the Church-Turing thesis. A common one is that every effective computation can be carried out by a Turing machine. The Church-Turing thesis is often misunderstood, particularly in recent writing in the philosophy of mind.

This paper proposes to examine Daniel Cohen’s recent attempt to apply virtues to argumentation theory, with special attention given to his explication of how open-mindedness can be regarded as an argumentational or critical virtue. It is argued that his analysis involves a contentious claim about open-mindedness as an epistemic virtue, which generates a tension for agents who are simultaneously both an arguer and a knower (or who strive to be both). I contend that this tension can be eased or resolved (...) by clarifying the nature of open-mindedness and by construing open-mindedness in terms of its function. Specifically, a willingness to take a novel viewpoint seriously is sufficient for making open-mindedness both an epistemic and a critical virtue. (shrink)

Some well-known metaphysical arguments against relativism rest on the claim that relativity somehow must be accompanied by relationality. I argue otherwise, and trace the consequences for some prominent disputes between relativists and absolutists.

In this paper, I argue that recent discussions of culprit-based epistemic injustices can be framed around the intellectual character virtue of open-mindedness. In particular, these injustices occur because the people who commit them are closed-minded in some respect; the injustices can therefore be remedied through the cultivation of the virtue of open-mindedness. Describing epistemic injustices this way has two explanatory benefits: it yields a more parsimonious account of the phenomenon of epistemic injustice and it provides the underpinning of a virtue-theoretical (...) structure by which to explain what it is that perpetrators are culpable for and how virtues can have normative explanatory power.

Much of the intuitive appeal of evidentialism results from conflating two importantly different conceptions of evidence. This is most clear in the case of perceptual justification, where experience is able to provide evidence in one sense of the term, although not in the sense that the evidentialist requires. I argue this, in part, by relying on a reading of the Sellarsian dilemma that differs from the version standardly encountered in contemporary epistemology, one that is aimed initially at the epistemology of (...) introspection but which generalizes to theories of perceptual justification as well.

To what extent are cognitive capacities, especially perceptual capacities, informationally encapsulated and to what extent are they cognitively penetrable? And why does this matter? Two reasons we care about encapsulation/penetrability are: (a) encapsulation is sometimes held to be definitional of modularity, and (b) penetrability has epistemological implications independent of modularity. I argue that modularity does not require encapsulation; that modularity may have epistemological implications independently of encapsulation; and that the epistemological implications of the cognitive penetrability of perception are messier than (...) is sometimes thought.

It is not widely realised that Turing was probably the first person to consider building computing machines out of simple, neuron-like elements connected together into networks in a largely random manner. Turing called his networks 'unorganised machines'. By the application of what he described as 'appropriate interference, mimicking education' an unorganised machine can be trained to perform any task that a Turing machine can carry out, provided the number of 'neurons' is sufficient. Turing proposed simulating both the behaviour of the (...) network and the training process by means of a computer program. We outline Turing's connectionist project of 1948. (shrink)

Logic and Reality is a collection of essays by philosophers, logicians, mathematicians, and computer scientists, celebrating the work of the late distinguished philosopher Arthur Prior on the eightieth anniversary of his birth. Topics range from philosophical discussions of the nature of time and of the nature of logic itself, to descriptions of computer systems that can reason and take account of the fact that they exist in a temporal world.

This paper provides a reply to articles by Nicola Angius and Guiseppe Primiero responding to our paper “Software Intensive Science”.

The tape is divided into squares, each square bearing a single symbol—'0' or '1', for example. This tape is the machine's general-purpose storage medium: the machine is set in motion with its input inscribed on the tape, output is written onto the tape by the head, and the tape serves as a short-term working memory for the results of intermediate steps of the computation. The program governing the particular computation that the machine is to perform is also stored on the (...) tape. A small, fixed program that is 'hard-wired' into the head enables the head to read and execute the instructions of whatever program is on the tape. The machine's atomic operations are very simple—for example, 'move left one square', 'move right one square', 'identify the symbol currently beneath the head', 'write 1 on the square that is beneath the head', and 'write 0 on the square that is beneath the head'. Complexity of operation is achieved by the chaining together of large numbers of these simple atoms. Any universal Turing machine can be programmed to carry out any calculation that can be performed by a human mathematician working with paper and pencil in accordance with some algorithmic method. This is what is meant by calling these machines 'universal'. (shrink)

Software-intensive systems are ubiquitous in the industrialized world. The reliability of software has implications for how we understand scientific knowledge produced using software-intensive systems and for our understanding of the ethical and political status of technology. The reliability of a software system is largely determined by the distribution of errors and by the consequences of those errors in the usage of that system. We select a taxonomy of software error types from the literature on empirically observed software errors and compare (...) that taxonomy to Giuseppe Primiero’s Minds and Machines 24: 249–273, (2014) taxonomy of error in information systems. Because Primiero’s taxonomy is articulated in terms of a coherent, explicit model of computation and is more fine-grained than the empirical taxonomy we select, we might expect Primiero’s taxonomy to provide insights into how to reduce the frequency of software error better than the empirical taxonomy. Whether using one software error taxonomy can help to reduce the frequency of software errors better than another taxonomy is ultimately an empirical question. (shrink)

There are many tangled normative and technical questions involved in evaluating the quality of software used in epidemiological simulations. In this paper we answer some of these questions and offer practical guidance to practitioners, funders, scientific journals, and consumers of epidemiological research. The heart of our paper is a case study of the Imperial College London covid-19 simulator, set in the context of recent work in epistemology of simulation and philosophy of epidemiology.

Near the end of the long and often convoluted discussion of freedom in the chapter ‘Of Power’ in An Essay concerning Human Understanding, Locke states that in ‘The care of ourselves, that we mistake not imaginary for real happiness, is the necessary foundation of our liberty’. He goes on to explain that ‘we are by the necessity of preferring and pursuing true happiness as our greatest good, obliged to suspend the satisfaction of our desire in particular cases’. Locke then adds (...) that the ability to suspend our desires in particular cases is ‘the hinge on which turns the liberty of intellectual Beings’. Unfortunately, this hinge has proved a serious stumbling block for commentators. After three hundred years, serious scholarly disagreement remains about even the central orientation of Locke’s views on freedom. Locke was aware of the opacity surrounding portions of his discussion of liberty. In letters to several correspondents, he confesses to almost leaving it out of the first edition, fearing that ‘the novelty and subtlety of the matter itself... [would be taken] as the paradoxes of an innovator or the stumblings of an ill-advised wanderer’. As evidence that his worries were not far wrong, Locke adds that amongst his friends, ‘more have entered into discussion with... [me] about this one subject than about all the remaining chapters of the book’. My entry into this controversy will be by way of Leibniz, one of Locke’s earliest and most astute commentators.

I am grateful that someone whose work I greatly admire could be the philosopher to so eloquently and succinctly cut to the heart of the problem that I posed in the previous issue of Deleuze Studies. James Williams' critical reply leaves me, prima facie, confronted by a stark alternative: either I have misunderstood Deleuze, or I have illustrated problems and lacunae in Deleuze. I will suggest, however, that this is a false alternative, and that Williams' and my divergent accounts of (...) The Logic of Sense – and even Deleuze's oeuvre as a whole – is better understood as a situation of ‘both/and’ rather than ‘either/or’, and hence that my interpretation of Deleuze isn't wrong, but necessarily iconoclastic.

As one of the preeminent philosophers of the twentieth century, W. V. Quine made groundbreaking contributions to the philosophy of science, mathematical logic, and the philosophy of language. This collection of essays examines Quine's views, particularly his holism and naturalism, for their value to feminist theorizing today. Some contributors to this volume see Quine as severely challenging basic tenets of the logico-empiricist tradition in the philosophy of science—the analytic/synthetic distinction, verificationism, foundationalism—and accept various of his positions as potential resources for (...) feminist critique. Other contributors regard Quine as an unrepentant empiricist and, unlike feminists who seek to use or extend his arguments, they interpret his positions as far less radical and more problematic. In particular, critics and advocates of Quine's arguments that the philosophy of science should be "naturalized"—understood and pursued as an enterprise continuous with the sciences proper—disagree deeply about whether such a naturalized philosophy is "philosophy enough." Central issues at stake in these disagreements reflect current questions of special interest to feminists and also bridge the analytic and postmodern traditions. They include questions about whether and how the philosophy of science, as a form of practice, is or can be normative as well as questions concerning the implications of Quine's philosophy of language for the transparency and stability of meaning. In representing feminist philosophy centrally engaged with the analytic tradition, this volume is important not only for what it contributes to the understanding of Quine and naturalized epistemology but also for what it accomplishes in working against restrictive conceptions of the place of feminism within the discipline. Aside from the editors, the contributors are Kathryn Pyne Addelson, Louise M. Antony, Richmond Campbell, Lorraine Code, Jane Duran, Maureen Linker, Phyllis Rooney, and Paul A. Roth. (shrink)

Deleuze suggests that his work grounds a new conception of the Other–the Other as expression of a possible world, as a structure that precedes any subsequent dialectical mediation, including the master-slave dialectic of social relations. I will argue, however, that the ethico-political injunction that Deleuze derives from his analysis of the 'other-structure' confronts a different problem. It commits Deleuze to either tacitly prescribing a romantic morality of difference that valorizes expressive encounters without 'relations of explication' and any kind of pre-understanding (...) (embodied or otherwise), or his continual flirtations with a mystical 'going beyond' the other-structure must be more than mere flirtations. (shrink)

In this insightful set of essays, the concept of the psychological humanities is defined and explored. A clear rationale is provided for its necessity in the study and understanding of the individual and identity in a discipline that is largely occupied by empirical studies that report aggregated data and its analysis. Contributors to this volume are leading scholars in theoretical psychology who believe that psychology must be about persons and their lives. In these essays, they draw from a variety of (...) disciplines that include art, literature, life writing, and history to make a case for the psychological humanities. A final chapter provides a critical commentary on the value of the psychological humanities. It is argued that psychology must draw on the knowledge and practices of the humanities, as well as the sciences and social sciences, in order to attain a greater understanding of personhood. This book is aimed at upper level undergraduate and postgraduate students and scholars of psychology, particularly theoretical psychology, philosophy of the mind, and those from a humanities background interested in exploring the concept of the psychological humanities.

In his story entitled "Toenails," the surgeon Richard Selzer (1982) warns readers that total immersion in medicine is wrongheaded. Rather, to ensure their own health, doctors should discover other passions that permit them periodically to disconnect from medical practice. Selzer's surgeon character devotes his Wednesday afternoons to the public library, where he joins "a subculture of elderly men and women who gather … to read or sleep beneath the world's newspapers" (p. 69). Among these often eccentric personages is Neckerchief, an (...) arthritic man in his 80s who suffers from severe foot pain. His toenails, never trimmed because of his inability to reach them, have grown so long that they curve beneath his toes and .. (shrink)

Hope helps alleviate suffering. In the case of terminal illness, recent experience in palliative medicine has taught physicians that hope is durable and often thrives even in the face of imminent death. In this article, I examine the perspectives of philosophers, theologians, psychologists, clinicians, neuroscientists, and poets, and provide a series of observations, connections, and gestures about hope, particularly about what I call “deep hope.” I end with some proposals about how such hope can be sustained and enhanced at the (...) end of life. Studies of terminally ill patients have revealed clusters of personal and situational factors associated with enhancement or suppression of hope at the end of life. Interpersonal connectedness, attainable goals, spiritual beliefs and practices, personal attributes of determination, courage, and serenity, lightheartedness, uplifting memories, and affirmation of personal worth enhance hope, while uncontrollable pain and discomfort, abandonment and isolation, and devaluation of personhood suppress hope. I suggest that most of these factors can be modulated by good medical care, utilizing basic interpersonal techniques that demonstrate kindness, humanity, and respect. (shrink)

In this paper I aim to develop a largely non-empirical case for the compatibility of phenomenology and naturalism. To do so, I will criticise what I take to be the standard construal of the relationship between transcendental phenomenology and naturalism, and defend a ‘minimal’ version of phenomenology that is compatible with liberal naturalism in the ontological register and with weak forms of methodological naturalism, the latter of which is understood as advocating ‘results continuity’, over the long haul, with the relevant (...) empirical sciences. Far from such a trajectory amounting to a Faustian pact in which phenomenology sacrifices its soul, I contend that insofar as phenomenologists care about reigning in the excesses of reductive versions of naturalism, the only viable way for this to be done is via the impure and hybrid account of phenomenology I outline here.

This paper addresses the question of whether Medicaid is in fact a high-cost program after adjusting for the health of the people it covers. We compare and simulate annual per capita medical spending for lower-income people (families with incomes under 200% of poverty) covered for a full year by either Medicaid or private insurance. We first show that low-income privately insured enrollees and Medicaid enrollees have very different socioeconomic and health characteristics. We then present simulated comparisons based on multivariate statistical (...) models that estimate the effects of private and Medicaid coverage on the likelihood of using services, and the level of expenditures, given any use, holding constant demographic, economic, and health status characteristics. The simulations demonstrate that if people with Medicaid coverage—with their health status, disability, and chronic conditions—were given private coverage, they would cost considerably more than they do today. Conversely, if the privately insured were given Medicaid coverage, spending would be lower. We find no evidence that spending differences between Medicaid and private coverage for low-income people are due to lower service use by Medicaid beneficiaries. We conclude that most of the difference in expenditures is due to differences in provider payment rates. (shrink)

Suggesting that phenomenology results in an “imperialism of the same” that considers the other only in terms of their effect upon the subject rather than in their genuine alterity, Levinas initiates a line of thought that can still be discerned in the work of Foucault, Derrida and Claude Lefort. However, this paper argues that Merleau-Ponty’s work is capable of avoiding this line of criticism, and that his position is an important alternative to the more dominant Derridean and Levinasian conceptions of (...) alterity. Moreover, this essay will also extricate Merleau-Ponty from Levinas’ claim that his philosophy is “sustained by an unaccountable affection”. Rather than ignoring the alterity of the other, and also without presupposing some primordial affectionate bond with the other, Merleau-Ponty explicates an interesting conception of what responsibility towards the ‘otherness of the other’ should consist in. Basically, he insists upon the way in which self and other are always already intertwined together (or reversible), and suggests that respecting the alterity of the other should involve the imperative to further immerse oneself in this transformative bond – to transform what we think of as self, and also what we think of as ‘other’.

Jack Crittenden examines the debate in political theory about the true conception of human nature. On the one hand is the concept of the liberal self which is self-contained, atomistic, even selfish; on the other hand is the notion of the communitarian self which is socially situated and defined in part by one's community. Crittenden argues that neither view is acceptable and draws on recent psychological research to develop a theory of `compound individuality'. The compound individual retains the liberal (...) emphasis on personal autonomy, without the association of autonomy with self-sufficiency. Crittenden concludes by reflecting on what kinds of political institutions will invite commitment and reflection from `compound individuals'. (shrink)

Nussbaum misconstrues the difference between Plato and Aristotle over what is real for a debate over a conception of truth. She seems to mistake Aristotle's arguments against Plato' version of realism as an argument against realism per se, though the texts do not permit such a reading. She claims Aristotle is convinced that realism involves a fatal “failure of reference,” yet she produces not a single text where Aristotle is even remotely concerned about such a failure of reference given the (...) commitments of realism. And nowhere is the crucial question of the relationship between Aristotle's antirealism and his method of appearances explicitly addressed or resolved.Nussbaum offers us a fashionable Aristotle. I have argued that, far from being attractive and obviously right on a deep and recent metaphysuical debate, Nussbaum's Aristotle is confused and inconsistent and thus that it is a good thing the texts do not support such a characterization.

Having initially not had the attention of Sartre or Heidegger, Merleau-Ponty's work is arguably now more widely influential than either of his two contemporaries. "Merleau-Ponty: Key Concepts" presents an accessible guide to the core ideas which structure Merleau-Ponty's thinking as well as to his influences and the value of his ideas to a wide range of disciplines. The first section of the book presents the context of Merleau-Ponty's thinking, the major debates of his time, particularly existentialism, phenomenology, the history of (...) philosophy and the philosophy of history and society. The second section outlines his major contributions and conceptual innovations. The final section focuses upon how his work has been taken up in other fields besides philosophy, notably in sociology, cognitive science, health studies, feminism and race theory. (shrink)
